CVE-2026-16437 lets a locally authenticated administrator defeat the forgotten-password recovery mechanism in Mitsubishi Electric's ICONICS-based GENESIS (11.03 and prior), GENESIS64, ICONICS Suite, Hyper Historian, AnalytiX, MobileHMI and IoTWorX (10.97.3 and prior) products, as well as all versions of MC Works64, GENESIS32 and BizViz, by tampering with the Windows-protected management file that stores the system-unlock challenge response - effectively unlocking the system without knowing the password. The impact ratings are high across confidentiality, integrity and availability, so a successful attacker could disclose, alter or destroy internal configuration data or drive the host into a denial-of-service condition. Realistic risk is tempered by the local-only vector, high attack complexity and the requirement for pre-existing administrative rights on the host; no public exploit identified at time of analysis, and no CISA KEV entry or EPSS score was supplied for this CVE. Vendor CVSS is 7.1 (HIGH).
Remote, unauthenticated attackers can unlock Mitsubishi Electric's ICONICS GENESIS, GENESIS64, ICONICS Suite and related SCADA/HMI products by obtaining the system's challenge-response unlock value, which the vendor confirms is fixed and identical for every user and every installation, after which the attacker can disclose, tamper with, destroy or delete internal information or force the system into a denial-of-service condition. Affected builds are GENESIS 11.03 and prior, GENESIS64/ICONICS Suite/Hyper Historian/AnalytiX/MobileHMI/IoTWorX 10.97.3 and prior, and MC Works64, GENESIS32 and BizViz at all versions. The vendor assigns CVSS 4.0 a 9.2 score, while our independent CVSS 3.1 assessment lands at 8.1 (AV:N/AC:H/PR:N/UI:N) because exploitation hinges on the one-time prerequisite of acquiring the static challenge response (the CVSS 4.0 AT:P attack requirement); no public exploit code and no confirmed active exploitation were identified at time of analysis, so the risk driver is the universal reusability of a single leaked value rather than any observed campaign.
SQL Server credentials are displayed in cleartext within the Hyper Historian Splitter GUI across multiple Mitsubishi Electric SCADA/HMI platforms (GENESIS64, ICONICS Suite, MC Works64, and related products), allowing local authenticated attackers with low privileges to capture database credentials and subsequently gain unauthorized access to backend SQL Servers. This affects versions 10.97.3 and prior for most products and all versions of MC Works64. No active exploitation confirmed (not in CISA KEV), though CISA has issued ICS advisory ICSA-26-097-01. With a CVSS 9.3 (Critical) score reflecting high confidentiality, integrity, and availability impact on both vulnerable and subsequent systems, the risk centers on credential theft enabling downstream SQL Server compromise.
Plaintext SQL Server credential storage in Mitsubishi Electric SCADA/HMI products allows local authenticated attackers with low-complexity exploitation to extract database credentials from SQLite cache files, enabling subsequent unauthorized SQL Server access for data manipulation and denial-of-service attacks. Affects multiple product lines including GENESIS64 ≤10.97.3, ICONICS Suite ≤10.97.3, and all MC Works64 versions when local SQLite caching is enabled with SQL authentication. CVSS 9.3 severity reflects extensive downstream impact potential (confidentiality, integrity, availability across both vulnerable system and connected SQL Server). No evidence of active exploitation (not in CISA KEV), but EPSS data unavailable and attack complexity rated low with only local authenticated access required.
